Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electric range,

The present invention relates to an electric range and a power control method thereof, and more particularly, to an electric range and a method of controlling the electric power of the burner when a plurality of burners are simultaneously turned on and the power consumption exceeds a maximum power allowable value. To an electric range that can be maintained preferentially and a method of controlling the electric range.

Electric ranges are widely used for various reasons such as being environmentally friendly, sufficiently stable, and easy to built in kitchens installed in kitchens. The electric range used in the kitchen is generally said to have a plurality of burners, which is essential in terms of the convenience of simultaneously heating a plurality of containers. For example, an electric range having three burners, such as a first burner having the largest output (thermal power), a second burner having a lower intermediate output, and a third burner having the weakest thermal power, .

When all the burners are turned on in the electric range having a large number of burners, the actual maximum allowable power value may be exceeded. That is, the power supplied to the general household has a maximum allowable power value. When all the burners of the electric range are simultaneously turned on, all the power consumption of these burners exceeds the allowable power value. This problem can be solved by designing so that the total power consumption of all these burners does not exceed the maximum allowable power value supplied to the home.

However, in consideration of the actual state of the heater being produced in general and the case where a large output is required in a burner used for domestic purposes, for example, the first burner described above uses a heater having a large output, And the third burner. When the output of the burner is selected in this way, there is a case where the total power consumption of all the burners exceeds the maximum allowable power value supplied to the home.

If the total power consumption of all the burners exceeds the maximum allowable power value, it can be solved through a separate electric work. However, such electric work tends to be disadvantageous to consumers because of the inconvenience and cost involved . In order to solve such a problem, Korean Patent No. 10-1263415 proposes a technique of adjusting the output as a whole when the sum of the power consumption of the burners turned on among a plurality of burners exceeds the allowable power value.

According to this conventional technique, a predetermined period is set for each burner, and when the sum of the power consumption exceeds the allowable power value, the time (timing) for turning on each burner within the cycle is not overlapped So that the maximum allowable power value is not exceeded.

However, according to the related art, when a part of the burners is currently turned on and another burner is turned on and the total power consumption exceeds the allowable value, the output of the burners that have been turned on according to a predetermined algorithm is lowered There is a problem that can not be solved. That is, the burner finally selected by the user has firepower corresponding to the output selected by the user, but the remaining two burners have to have a reduced output according to the predetermined algorithm.

Generally, a person who mainly uses an electric range is set in a kitchen, and the usage pattern is usually repeated according to a user-defined routine. For example, a main user of a kitchen may be said to be one person, and a pattern in which such a user uses an electric range often repeats the same thing. Therefore, it can be said that the user has a certain degree of output among the plurality of burners of the electric range as the most used or the most preferred ones.

The fact that the user has the most used burner and the degree of the output of the burner among the burners of the electric range is that it is preferable that the burner preferred during heating using a plurality of burners should be outputted as close to the preferred output as possible it means.

As described above, the burner finally selected by the user will have a firepower corresponding to the output selected by the user, but the remaining two burners have to have a reduced output according to a predetermined algorithm. Thus, for example, if the first burner is set to the maximum power level and the power consumption of all the burners exceeds the allowable power value, the second burner and the third burner are automatically set back to the determined reduced output. That is, the two burners (the second burner and the third burner) excluding the burner finally selected by the user (for example, the first burner) are set to predetermined outputs irrespective of the user's intention, Can be raised.

In this state, when the user performs an operation to increase the output of the second burner, the power consumption is exceeded by the increase of the output of the second burner, and accordingly the output of the first burner or The output value of the third burner is automatically set to decrease. That is, according to the conventional technique as described above, the selection of one burner causes the inconvenience of using the other burners because the other burners are automatically set to the predetermined output irrespective of the user's preference .

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and it is an object of the present invention to provide an electric range and a control method thereof in which the burners other than the burner finally selected by the user in the electric range having a plurality of burners can be distributed according to the user's preference .

An electric range of the present invention includes: a plurality of burners each having a sum of power consumption exceeding an allowable power value; An input unit capable of selecting an on-off and an output level of the burner, and inputting priority information for a priority burner preferentially controlled among the plurality of burners; A storage unit for storing priority information inputted through the input unit; And controls the burner on / off and the output level based on the input of the input unit, and controls the input unit to receive the priority information for the priority burner. When the sum of the power consumption of the burner exceeds the allowable power value, And a control unit for controlling the output of each burner based on the priority information stored in the burner.

The priority information input through the input unit may include not only the burner but also the output level of the burner which is preferentially controlled.

According to the embodiment, when the sum of the power consumption by the finally selected burner and the selected output level exceeds the allowable power value, the control unit keeps the finally selected burner at the selected output level and outputs the output based on the priority information among other burners Respectively.

According to another embodiment, when the sum of the power consumption by the finally selected burner and the selected output level exceeds the allowable power value, the control unit firstly maintains the current output of the burner, and the finally selected burner has the range of the allowable power value So as to correspond to the input level.

A power control method of an electric range of the present invention is a control method of an electric range having a plurality of burners in which a sum of power consumption exceeds an allowable power value, process; Determining whether a sum of power consumption of the plurality of burners exceeds an allowable power value; If the sum of the power consumption exceeds the allowable power value, the finally input burner maintains the output at the selected level, and the priority burner among the remaining burners is controlled to have a relatively higher output than the other burners .

According to the present invention as described above, it is understood that even if the sum of the power consumption of a plurality of burners exceeds the allowable power value, the output of the burner most frequently used by the user can be maintained most favorably. Therefore, when the electric range and the control method according to the present invention are applied, it is possible to provide an electric range which is most convenient for usual habits including cooking patterns and the like.

Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings. As shown in FIG. 1 in which an electric range to which the present invention is applied is exemplarily shown, the electric range of the present invention has a plurality of burners, for example, a first burner 2 having the largest output, , And a third burner 6 having the smallest output. The first burner 2 having the largest output has two heaters, and the second burner 4 and the third burner 6 each have one heater.

Here, the first burner 2 having the largest thermal power can selectively turn on the two heaters, for example, the first heater can be turned on and the first heater and the second heater can be turned on at the same time. The output of the first burner 2 is controlled by the control unit 10 by the user through the input unit 8, which will be described later. For example, when the large burner "expansion" key installed in the input section 8 is turned on, the first heater and the second heater of the first burner 2 are simultaneously turned on.

The output level of each of the burners 2, 4 and 6 can be adjusted independently of each other, for example, the output level can be set to a first level with the lowest output and a ninth level with the highest output, have. That is, the user can select a desired output level while turning on each burner, and the output level will be described later.

 Here, if all the burners 2, 4, 6 are turned on and a power level equal to or higher than a certain level is selected, the sum of the power consumption of the burners 2, 4, 6 exceeds the allowable power value for household use (for example, 3500 W) . Here, even if any of the heaters of the first burner 2 is operated (i.e., even if the extension function of the large burner is not used), the sum of the power consumption of all the burners 2, 4, 6 exceeds the allowable power value . The sum of the power consumption of all the burners 2, 4 and 6 exceeds the allowable power value even when the extension key of the first burner 2 is selected and both the first heater and the second heater are turned on. Do.

When the second burner 4 is turned on while two heaters of the first burner 2 are turned on and a power level equal to or higher than a certain level is selected, the sum of the power consumption exceeds the allowable power value. However, even if the two heaters of the first burner are turned on, the output of the third burner is relatively low, so that the sum of the power consumption does not exceed the allowable power value even when the power is turned to the maximum output level.

Therefore, when the sum of the consumed electric power exceeds the allowable electric power value even when all of the three burners 2, 4 and 6 are used or when two burners are used, the sum of the electric power consumption exceeds the allowable electric power value The control unit 10 controls the time for turning on each burner.

That is, a predetermined time period (for example, 30 seconds or 40 seconds) is set for all of the burners 2, 4 and 6, and for each burner so as not to exceed the allowable power value within one cycle So that the on-time is controlled. This time control can be said to be a technique already proposed in the above-mentioned prior art. Through such time control, all the burners are used at the same time, but the control is performed so as not to exceed the allowable power value.

The output of each of the burners 2, 4, 6 can be controlled in multiple stages through the time control for turning on the respective burners within one cycle. For example, Is set to 1 stage, which is the lowest output, it is controlled to keep the OFF state for 39 seconds and ON state for 1 second when 40 seconds is set as one cycle. When the burners 2, 4 and 6 are set to the maximum output of 9 stages, the control is performed such that the ON state is always maintained in one cycle.

Thus, the input unit 8 is provided for setting the on / off state of the burners 2, 4 and 6 and the levels of the output values (for example, first to ninth levels). Therefore, when the user turns on or off the first burner (2) to the third burner (6) through the operation of the input unit (8), when the user turns on the output of each burner, Can be input. According to the present invention, it is possible to select a burner to be preferentially used by the user through the input unit (8).

 Hereinafter, the electric range of the present invention will be described in more detail with reference to FIG. As described above, the input through the input unit 8 is transmitted to the control unit 10, and the control unit 10 controls the first burner 2 to the third burner 6 based on the input of the input unit. For example, it is possible to turn on or off the switching elements 16 corresponding to the respective burners 2, 4 and 6, to control the burners 2, 4 and 6 to the output levels inputted through the input section 8 .

According to the present invention, the user is configured to be able to select his or her preferred burner and its output level. For example, when the power is turned on for the first time or the sum of the power consumption of the burners (2, 4, 6) exceeds the allowable power value, the following functions can be performed. When the power is turned on for the first time, the control unit 10 allows the user to determine which of the burners (2, 4, 6) is to be preferentially controlled.

That is, the control unit 10 notifies the user through the display 18 which of the burners 2, 4 and 6 should be preferentially controlled, and the user can select the burner to be controlled preferentially through the input unit 8 . The priority information on the burner selected by the user, that is, the burner is input to the storage unit 12 first.

The selection of the priority burner by the user as described above can also be performed when there is an input in a range where the power consumption of the burners 2, 4, 6 during use exceeds the allowable power value. When selecting and inputting the priority burner, the output level that should be the highest priority among the output levels of the corresponding burners can also be input. For example, since the user uses the second burner 4 the most, it is possible to preferentially select a specific output level from the output level 1 to the output level 9 of the second burner 4 when the burner is first designated Priority information for the output level).

Hereinafter, the actual control process of the electric range of the present invention will be described. First, when some or all of the three burners (2, 4, 6) are turned on and the sum of their output levels does not exceed an allowable power value (for example, 3500 W) . That is, since the output level selected by the user is low, if the current for a desired level of output can be supplied to all the burners (2, 4, 6) within one cycle, do.

When the three burners 2, 4, 6 are turned on at the same time or the sum of the output levels when the two burners 2, 4 are turned on exceeds the allowable power value, the following control is performed. As shown in Fig. 3, when a specific burner is turned on (S102), the controller 10 determines whether the total power consumption exceeds the allowable power value (S104). Since the control unit 10 knows the power consumption of each of the burners 2, 4 and 6 and the power consumption at each level, the control unit 10 calculates the power consumption based on the output level selected in each of the burners 2, Can be calculated. If it is determined in step 104 that the sum of the power consumption does not exceed the allowable power value, the general control is performed in step 106. Here, the general control means that each of the burners 2, 4 and 6 outputs the output level value specified by the user as described above.

As a result of the determination in operation 104, if it is determined that the sum of the power consumption of the burner exceeds the allowable power value, the control proceeds to operation 108, and the control is firstly performed. Here, the priority control is a control that is inputted through the input unit 8, and based on the priority information (priority information on the burner and / or priority information on the output of the designated burner) stored in the storage unit, , 4, 6).

That is, as described above, the user inputs and stores a burner having a priority order among a plurality of burners through the input unit 8. Therefore, the "priority control" in the present invention means that the control unit 10 controls the burners 2, 4, and 6 based on the priority information input to the storage unit 12. [ The priority control is based on the following embodiment, wherein the control is performed when the sum of power consumption of substantially all of the burners exceeds the allowable power value.

This priority control is a case in which three burners 2, 4, 6 are turned on at the same time. For example, it can be said that, when a part of the burners is turned on and the other burners (for example, the first burner) are turned on while the burners are being turned on, the total power consumption exceeds the allowable power value . In this case, both of the two heaters of the first burner 2 at the maximum output can be caused to be in an ON state, and even when one heater is in an ON state.

In this case, in the first embodiment, the finally selected burner (first burner) maintains the output level selected by the user and preferentially outputs the burner set by the user in the priority order among the remaining burners . For example, in a state in which the user designates the second burner 4 as a priority order through the input unit 8, the power consumption of all the burners is determined by the output level selected while the user finally selects the first burner 2 It can be assumed that the allowable power value is exceeded. In this case, as shown in FIG. 4, the control unit 10 keeps the output level of the first input burner 2 selected by the user (Step 202), and the control unit 10 controls the second burner 4 And controls to distribute the output preferentially to the second burner 4 among the third burners 6. [

That is, during one cycle (for example, 30 seconds or 40 seconds), the first burner 2 outputs (e.g., keeps on for 26 seconds in a period of 40 seconds) at a set level and the second burner 4 and the third burner 6 are controlled to be in an ON state for a time not overlapping with the first burner 2. When the second burner 4 is first designated as a burner, Means to preferentially distribute the time allocation (within the cycle) to the remaining power consumption, for example, 70% or 80%. Here, preferentially distributing the time within one period can be said to have substantially the same meaning as controlling the magnitude of the output in priority.

In this case, if the priority information on the output level of the second burner 4 is input in advance through the input unit 8 in step 204, it is controlled to match the priority level of the second burner 4 , It may be controlled by the control unit 10 so as to have an output level at least close to the output level.

As an example of the second embodiment, priority information (priority information on the burner and priority information on the output level) is preferentially processed over the final input. For example, in a state where the user designates the second burner 4 as a priority burner through the input unit 8, the power consumption of all the burners is determined by the output level selected while the user finally selects the first burner 2 It can be assumed that the allowable power value is exceeded.

In this case, in the second embodiment, as shown in Fig. 5, even if the first burner 2 is finally inputted, the second burner having priority information is preferentially outputted. Here, it is also possible to perform control based on the priority information on the output level of the second burner. For example, assume that the second burner is designated as a priority burner and its output level 7 is designated as priority. When the first burner 2 is finally input in this state, the output of the second burner 4 designated first in step 202A is maintained at a desired level or a predetermined output level. Then, in step 204A, the output of the first burner 1 and the output of the third burner currently being output are controlled within the allowable power consumption range. Even in this case, it is preferable that the first input burner is controlled so as to have an output that is closer to the input level than the third burner.

The above-described priority control has been described as an example in which the sum of the power consumption exceeds the allowable power value while three burners are simultaneously turned on. However, it is needless to say that the present invention is not limited to this, and the present invention can also be applied to a case where the sum of power consumption exceeds the allowable power value while the first burner and the second burner are turned on.

For example, if the second burner 4 is designated as a priority burner and the output level 7 is stored as priority information, the first burner is finally input at a predetermined output level, The case where the power value is exceeded can be considered. In such a case, the control unit 10 will control the output of the first burner within a range allowed by the power consumption, while maintaining the stored output priority level of the second burner as the stored priority information.

According to the present invention as described above, the basic technical idea is to store the burner used most frequently by the user and priority information on the output, and to control the output of the electric range based on the priority information . It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
